Set MAP-T Disable Profile

[Chrisee]

@Shonk_ Well you appear to know Sky's business better than the Sky staff who brief the Forum Super Users so dont think I can add anything except we have seen zero reports of MAP-T affecting users of Asis routers.

Im a big fan of sky's old easynet core network it was maintained second to none

they where the first in the uk to go 100G backhaul for example with good peering to all pops 

hopefully it hasnt degraded since i left in 2021

most complaints in the past about sky was poor internal wiring on dsl lines or wifi complaints

i know i will get zero issues atm but at some point in the future think 5 or 10 years

they will force upgrade legacy users to newer router's once there isnt many left in the wild

so its good to get opted out now so im in the database on dual stack and not MAP-T

so with luck i wont get forced onto it when the time comes

@Shonk_ in 10 years time we will all be using IP6 so the issue disapears. 

[Shonk_]

lol i have been running a dual stack for 16 years

the whole time people have been saying that

Which from did you use to request this, I need to get it disabled on my connection so I can get my VPN to work at home?

If you need to contact Sky (as your duplicate thread indicated), just dial 150 free from your Sky Talk landline.

I have Openreach coming to install fibre on the 12th of May and thats when my Sky Gigafast is going live too. 

I'm currently using Unifi Cloud Gateway Ultra and will have 2 WAN connections. The current full fibre connection (not Openreach Fibre) will be used as a failover over connection and the Openreach Sky Gigafast will become my primary internet connection once installed and activated. 

I, like @Shonk_  "run various services and servers over my connection including my own VPN server and various other servers" 

To be prepared for the 12th May install/Go live date, I've setup my Cloud Gateway ultra to use the 2.5Gb WAN port as the following. 

Because the servers i have at home amongst other things will act as a backup site (over a wireguard connection) for mine and my wifes companies. I can not have MAP-T IPv4 address sharing. 

So few points...i guess.

1) Are the settings in Unifi correct?

2) @Shonk_  mentioned "option 60 on IPv4 has to not have MAPT1 in the string". From what i've seen online Option 61 is what needs to be selected to use a non-sky router. 

3) Unifi although not supported and doesn't have the option, responds to DHCPv6 Client Option 95. Which from what i've read breaks things.

I would also like the MAP-T profile provision to be removed from my SKY Account before the install date. So that i'll have an easy trouble free connection and everything will work exactly the way it works right now.

Thank you in advance

@Ron-C  answering your questions to the limit of my knowledge

1) I am no expert on Unifi routerscbut it looks correct

2) The option required is 61 not 60 if using the DHCPv4 method.  The simpler DHCPv6 PD system which does not require a string and works on over 80% of Openreach lines.

3) to get a  MAP-T connection the router must advertise support for DHCPv6 Option95 which the Sky Max hubs do so if your Unifi doesn't this isnt an issue. Note Sky will only remove MAP-T if there is a technical issue that requires it they do not offer that option on request.

Sky are selling a domestic connection for "private use by you and your household" so your use case is not something they support and to get support forca line issue you will be required to have the Sky hub connected as their diagnostics require it.. Sky are very much you get what you are given ISP if you require adjustments etc they are not ghe ISP for you.

[Ron-C]

thanks for your reply @Chrisee 

So to avoid MAP-T altogether is to disable DHCPv6 in Unifi and just leave DHCPv4 set to option 61.

[Chrisee]

@Ron-C no need to disable DHCPv6 given the lack of support for Option95.instead use DHCPv6 to get a dual stack connection. 

[Ron-C]

I've dug around on the sky forum a little more and came across this thread.

https://helpforum.sky.com/t5/Broadband/Sky-Fibre-amp-Unifi-Dream-Machine/td-p/4735135

It says the Unifi gear doesn't play well when DHCPv6 is enabled and the only way around it would be to disable DHCPv6. Though not recommended. I'll have to disable DHCPv6 and run v4 only

[Chrisee]

@Ron-C that is out of date.  For roughly 8 years Unifi routers adverised DHCPv6 Option95 while they dod not in fact support MAP-T around 2 years ago Unifi belatedly sorted their mistake in a firmware release. So as long as your unit is running reasonably up to date firmware you should be fine this is confirmed in post52 of that thread.
